需要解决sor-thumbnail错误的帮助:“'thumbnail'不是有效的标签库:" [英] need help solving sorl-thumbnail error: "'thumbnail' is not a valid tag library:"
问题描述
我一直在努力解决此问题，我已经做了所有尝试，但我没有想法.
I've been pulling my hair out trying to solve this problem and I've tried everything and I have no ideas left.
我一直看到此错误:异常值:'thumbnail'不是有效的标记库:无法从django.templatetags.thumbnail加载模板库，没有名为sorl.thumbnail.main的模块
I keep seeing this error: Exception Value: 'thumbnail' is not a valid tag library: Could not load template library from django.templatetags.thumbnail, No module named sorl.thumbnail.main
$ DJANGO_PACKAGES/sorl/thumbnail/main.py存在.
$DJANGO_PACKAGES/sorl/thumbnail/main.py DOES exist.
这就是我要做的设置
-
下载了最新的sorl-thumbnail，并将其位置添加到.bash_profile中的python路径
downloaded latest sorl-thumbnail and added its location to the python path in .bash_profile
在INSTALLED_APPS中包含了"sorl.thumbnail"(在Django的settings.py中)
included 'sorl.thumbnail' in INSTALLED_APPS (in django's settings.py)
在Django模板中使用了{％load thumbnail％}标签
used the {% load thumbnail %} tag in a django template
很明显，未正确安装sorl-thumbnail，但是我能够从python shell和django shell导入缩略图(当我使用{％load thumbnail％}时会出现此错误).另外，相关文件中没有错别字(我已经检查了很多次).
It would seem obvious sorl-thumbnail is not installed correctly, but I'm able to import thumbnail from the python shell and the django shell (when I use {% load thumbnail %} it brings this error). Also, there are no typos in related files (I've checked many many times).
推荐答案
我敢猜测这是一个$ PYTHONPATH问题."thumbnail"目录是否在路径上，而不是在"sorl"目录下?我怀疑这是问题所在，因为您不想在Python解释器上键入导入缩略图".您应该改为键入"import sorl.thumbnail".
I would venture to guess this is a $PYTHONPATH issue. Is it possible that the "thumbnail" directory is on the path and not "sorl"? I suspect this is the issue because you do not want to be able to type "import thumbnail" on the Python interpreter. You should instead have to type "import sorl.thumbnail".
要检查的另一件事是在导入后打印模块名称:
Another thing to check is to print the module name after importing:
>>> import thumbnail
>>> print thumbnail
这将显示找到该模块的文件系统位置，以防它正在从您不希望的地方加载另一个副本.
This will display the filesystem location where the module was found, in case it's loading another copy from somewhere you do not expect.
您还希望确保当前的工作目录不是../sorl/根目录(即，不要从sorl文件夹运行python).这将使您可以直接导入缩略图.
You also want to make sure your current working directory is not the root ../sorl/ location (ie. don't run python from the sorl folder). This will allow you to import thumbnail straight-away.
您应该从python解释器中检查完整的Python路径(该路径将超过$ PYTHONPATH)，以验证您的包位置:
You should check your full Python path (it will be more than $PYTHONPATH) from within the python interpreter to verify your package locations:
>>> import sys
>>> print sys.path
